Rain barrels are containers designed to collect and store rainwater from rooftops through gutters and downspouts. They are typically made of plastic or wood and can hold varying amounts of water, often ranging from 50 to 100 gallons. By capturing rainwater, these barrels help conserve water and reduce runoff, making them an eco-friendly choice for gardening and landscaping. Using rain barrels can also lower water bills, as homeowners can use the stored rainwater for watering plants, washing cars, or other outdoor activities. Many rain barrels come with a spigot for easy access and may include a screen to keep out debris and insects, promoting clean water storage.
